how much does it cost and what parts are needed

You can get chinkesium turbos on ebay for like 200 bucks. But by the time you add all the details up, it ain't budget anymore. I've seen where people stomp through junkyards and such scrounging up crap, but who has time for that? Not to mention, you will probably end up with what junkyards are known best for. Junk. I'll go even farther and say the words budget and car hobby don't even belong in the same sentence anymore.
